Garage kits are amateur-prouced model kits. The term originated with dedicated hobbyists frustrated with being unable to find model kits of subjects they wanted on the market and so started producing kits of their own. As the processes of sculpting, casting and painting produce dust and fumes, most of the sculptors used their garages as their workshops, hence the name. Originally these kits were sold and traded between hobbyists at conventions, such as WonderFestival, but they have since gained popularity and now there are a number of companies, including Federation Models, Volks, WAVE/Be-J, Kaiyodo, Kotobukiya, and B-Club, producing these kinds of kits professionally.
